Metabones speedboster true aperture

21 March 2018 - 07:21 AM

Hi all :)

 

When using a metabones speedboster, how do you really gauge the true aperture the lens is giving you? I mean from a practical point of view, you keep it mind that you get +1 stop of light hitting the sensor. 

 

But from a tech point of view, if your lens is set at let’s say 2.8 (and it’s the fastest the lens can get to), does the camera shows you the added stop? Or is it a passive speedboaster that doesn’t trasmit aperture values?

 

In case it doesn’t trasmit that, you just keep in mind that if the lens is set at 11, you could set f/8 on your light meter?

 

So in practice can you use a ND 0.3 paired to the speedbooster to get a slightly shallower depth of field without having to change your lens aperture?

 

 

Thank you, 

Stefano
